DH is beside himself; He says to get a lawyer and sue the pants off of them! This is discrimination and it can't be allowed to happen again. Call the ALCU or something!! Get your life and dignity back, and maybe, never work again!! I'm sure you could find a Pro-Bono attorney in this case!!!
Further, I don't see a need to send a letter to the Super, How dare that person! Clearly you have been cleared, you have a letter about MS, your doc's support you....I like the "Call the local News Media" Idea as well. I really hope you put the school district in their place and take action. I think a huge suit is the best thing you can do. Here you've been cleared and they STILL have not apologized or rectified this situation.
SO WHAT if she thought you were on drugs or drinking! YOU WERE NOT and you told that stupid woman you had MS. She should have called medic's, not DFS! Oooohhhh! Okay, Off my soapbox now.
You don't have to suffer anymore....please stand up for your rights!
